This is the order of the standard armor from strogest going down daedric, elven, ebony, darksteel,glass,steel, mithril, iron.but personaly i prefer glass because it looks ok and it has no major weaknesses ie with daedric holy weapons cut straight through. But if you want the best armor ever get the frostcrag spire pack and make your ownhave fun experimenting just remember to keep lots o cash in ur pocket

Dadric aroumor. It drops of any heavy huminods at level 20. Eg maruders, vamps. It works best if you have mastered the mages guild so the you can enhance the armour to what suits you. PS- Dadric is very heavy so if you prefer light armour go with glass.

get to level 20+ with finishing the mainstory. i should say that you should have a fairly high defence and strength, once inside "roxen inn" north of imperial city, sneak behind the pack of glass armored group and one female with daedric all huddling, if you have high conjuration and mana, summon a skeleton guardian or use the scroll to summon rufio if you still have it. Then wear the gray nocturnal cowl(if finished thieves guildlines) if not then this might be a bit more difficult. Then just slice the daedric user with a 6x damage. The daedric and glass armor tend to run out of the inn. Their is a imperial legion guard in there, but do not bother to hit him first. As the daedric female will flee. Fight him off last. he shouldn't come talking to you as he will be concentrated on the NPCS fighting on him and the summon you had summoned.

Tips:Finishing some daedric shrine quests that give you chameleon, ex. Ring of khajit.
